This section gives an overview of quota system in BASE and how the disk usage is kept track of.
QuotaData holds information about a
single quota registration. The same quota may be used by many different users
and groups. This object encapsulates allowed
quota values for different types of quota types and locations.
BASE defines several quota types (file, raw data and experiment),
and locations (primary, secondary and offline).
DiskConsumableData (for example a file)
item is automatically linked to a
item. This holds information about the number of bytes,
the location and quota type the item uses. It also holds information
about which user and group (optional) that should be charged for the disk usage.
The user is always the owner of the item.
